It delivers up to 20 Mbps data rate with 2500 Vrms galvanic isolation and 30 kV/µs common-mode transient immunity, making it suitable for noise-prone industrial networks, motor drives, and instrumentation where ground loops must be broken. ## 2500 Vrms isolation and 30 kV/µs CMTI — what they mean for a noisy bus The 2500 Vrms isolation rating is the withstand voltage between the logic-side and bus-side domains, tested per the component-level standard. Combined with 30 kV/µs common-mode transient immunity, this part handles the fast voltage transients found in variable-frequency drives and switched-mode power supplies without corrupting the data stream. The 20 Mbps data rate supports Profibus and other high-speed RS485 protocols. ## -55°C to 105°C — military temperature grade for harsh environments Most isolated RS485 parts top out at 85°C; the LTM2881MPY-3#PBF's extended range is a differentiator for engine-bay, solar-field, or outdoor telecom equipment where ambient heat is a factor. ## Integrated isolated power — one part replaces three The µModule includes an on-chip isolated DC/DC converter, so no external transformer or separate isolated supply is needed. This saves board area and simplifies the BOM compared to discrete approaches using a separate isolator, transceiver, and isolated power module.","metaTitle":"LTM2881MPY-3#PBF Isolated RS422/RS485 Transceiver, 20Mbps","metaDescription":"LTM2881MPY-3#PBF µModule isolated RS422/RS485 transceiver with integrated power. 20Mbps data rate, 2500Vrms isolation, -55°C to 105°C.","metaKeywords":null},"attributes":{"series":"µModule®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"RS422, RS485","Series":"µModule®","Package":"Tray","Data Rate":"20Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"32-BBGA Module","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Operating Temperature":"-55°C ~ 105°C","Inputs - Side 1/Side 2":"1/1","Supplier Device Package":"32-BGA (15x11.25)","Common Mode Transient Immunity (Min)":"30kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$44.96","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$44.96000","currency":"USD"},{"qty":10,"price":"$41.94800","currency":"USD"},{"qty":25,"price":"$40.19000","currency":"USD"},{"qty":119,"price":"$36.42210","currency":"USD"},{"qty":238,"price":"$35.16618","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/2881fj.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum data rate of LTM2881MPY-3#PBF?","answer":"The maximum data rate is 20 Mbps, suitable for high-speed RS422/RS485 protocols like Profibus."},{"question":"Is LTM2881MPY-3#PBF compatible with 3.3V systems?","answer":"Yes, the supply range of 3V to 3.6V covers 3.3V rails directly."},{"question":"Can LTM2881MPY-3#PBF replace LTM2881IY-3#PBF?","answer":"The LTM2881MPY-3#PBF is the extended-temperature variant (-55°C to 105°C) of the LTM2881 family.
